摘要： The invention relates to an electromotor comprising a stator part and a rotor part, which parts form an oil-containing spiral groove bearing system. Surface areas of said parts are provided with a so-called oil barrier in order to prevent the oil from creeping from the bearing system to the environment. According to the present invention, said oil barrier comprises a monolayer of perfluorocarboxylic acid anions, especially those having a chain length of 10-20 C-atoms and/or perfluoroalkylthiol anions. Oil barriers of this type can be easily provided on the rotor part and stator part by means of dipping. These oil barriers have a very small thickness and can very suitably be used to prevent oil creepage.

摘要： A package of a semiconductor device comprising an integrated circuit (10) generally comprises an inner layer (21) and an outer layer (16), which layers (16,21) have a mutual interface (24). An improved stability of the package is realized in that the interface (24) encloses a delamination area (22), which area (22) is isolated from any bond pads (18) of the integrated circuit (10). The delamination area (22) may be created by a pattern-wise activation of a surface of the inner layer (21). A quantity of a curable polymer may be disposed on this surface to achieve this.

摘要： An X-ray examination apparatus (1) comprises a filter (4) which is arranged between the X-ray source (2) and the X-ray detector (3). The X-ray filter comprises a large number of filter elements (5); the X-ray absorptivity of said filter elements can be adjusted by controlling the quantity of X-ray absorbing liquid (6) in the filter elements. The filter elements are formed by metal capillary tubes, or the wall of the capillary tubes is provided with a metal layer (7). On the metal layer there is provided a dielectric layer (8) and the dielectric layer is covered by a coating layer (9). The dielectric layer is, for example a glass, parylene or polystyrene layer. The coating layer is, for example a Teflon, silane of siloxane layer. The dielectric layer can be dispensed with when a Teflon coating layer is used.
